In 2023, a California materials scientist built a device that pulled drinking water from desert air; it produced 35 litres a day at just 20% humidity

A team of scientists has engineered a groundbreaking solar-powered device designed to extract moisture from desert air. Utilizing a unique MOF material, this inventive machine captures and subsequently releases water vapor. Notably, it succeeded in generating potable water in the extreme conditions of Death Valley while also performing admirably in the more humid climate of Berkeley. This innovation marks a pivotal step forward in passive water harvesting technology.
